Usage guidelines
A primary VLAN can be associated with multiple secondary VLANs. When you execute this
command in the same VLAN view multiple times, all the specified secondary VLANs are associated
with the primary VLAN.
The configuration synchronization is triggered based on the interface configuration when the
following conditions exist:
•
This command is configured for a primary VLAN.
•
Ports on the device are promiscuous, trunk promiscuous, or host ports.
When you execute the undo private-vlan command, follow these guidelines:
•
If you specify the
secondary vlan-id-list
option, this command dissociates the primary
VLAN from the specified secondary VLANs.
•
If you do not specify the
secondary vlan-id-list
option, this command dissociates the
primary VLAN from all secondary VLANs.

# Associate primary VLAN 2 with secondary VLANs 3 and 4.
<Sysname> system-view
[Sysname] vlan 3 to 4
[Sysname] vlan 2
